5G Generation Application and RF Filter Duplexer Combiner/Splitter – TEMWELL TEMSTRON

 
5G technology is a breakthrough, delivering Enhanced Mobile Broadband (eMBB), Ultra-Reliable and Low-Latency Communication (URLLC) and Massive Machine-Type Communication (mMTC), 5G applications represent tremendous opportunities for consumers, homes, businesses and communities.

 

How 5G can be faster? The main reason should be using shorter frequencies (millimeter waves between 30GHz and 300GHz) and larger the bandwidth. The high-band 5G spectrum supports expected boost not only in speed but also in capacity, low latency, and quality. However 5G download speed may differ widely by area. In addition to speed enhanced, 5G also hope to unleash massive IoT (Internet of Things) ecosystem networks can serve communications need for billions of connected devices.
 

Each new generation wireless network came with all new set of new usages. 5G will make no exception and will be focused on IoT and critical communications applications.

New 5G applications are emerging, supported by national strategies:

l  Telecom: 5G for mobile and home networks facilities (e.g. Fixed Wireless Access, smart phone, data center, cloud server, base transceiver station, gateway, TV and video service enhanced etc)

l  Manufacturing: smart factories & connectivity over the full product lifecycle (e.g. industry 4.0, Internet of Things (IoT), remote control machines, robots, RFID sensor, smart power grid, process automation etc)

l  Transportation: vehicle-to-everything (V2X) communications, remote driving, in-car infotainment (e.g. autonomous driving, drone delivery, video capturing, GPS enhanced, weather radar and location-based services etc), smart railway, airport

l  Public services: real-time healthcare (e.g. telemedicine, remote surgery with robots, medical (wearable) devices connections etc), education

l  Media: AR/VR gaming and advertising, multi- broadcasting


The 5G spectrum frequencies contain the sub-6 GHz and the millimeter-wave (mm-Wave) from 24.25 GHz and above. In the sub-6 GHz range still major for 4G LTE, GSM, ISM, RFID, WLAN, Wi-Fi 6E, GNSS, Tetra, Project 25, NB-IoT, WCDMA, LPWAN related technologies and applications; Satellites use frequencies near or in the mm-Wave range, therefore will be sharing the space with 5G traffic. How to coexist and how to resolve signal interference conflicts deserves research and attention. Therefore the RF & Microwave Filters, Duplexers and Combiners or Splitters play an increasingly vital roles to resolve signal interference conflicts.

Custom Solution:
TEMWELL group (Temwell and Temstron) is the go-to technology innovator for complete RF passive component solutions and 5G support. We design and manufacture various standard and customizable designs for Bandpass, Bandstop, Notch, Lowpass, Highpass Filter, Duplexer, Diplexer, Triplexer, multi-way Combiner, Splitter, Power Divider, as well as other RF components e.g. Circulator, Isolator, Coupler, Attenuator and Amplifier.

 
Our products are primarily supporting to work from DC to 60 GHz, narrow and broadband, low power and high power (200W+), low group delay, low insertion loss, flat ripple, high attenuation(rejection) ( 80dB+), also passive inter-modulation (PIM), and indoor & outdoor(waterproof IP-graded e.g. IP66, IP67). We have technologies including: Helical, Cavity, Comb, Interdigital, Stripline, Microstrip, Waveguide, LC, Dielectric (DR) and Ceramic etc.
